Students explore the properties of rectangular prisms. In this geometry lesson plan, students identify properties of two and three dimensional shapes. They use Cabri technology to create polygons and solve problems.

Students are introduced to the notion of surface area and volume. Students review surface area and volume by finding the area of a two-dimensional shape. They practice using the computer to create different surface area shapes.

Second graders explore triangles and quadrilaterals. They rotate to various centers in the room to identify and examine triangles and quadrilaterals. After presenting a picture to the class, 2nd graders locate right angles, triangles...

Fifth graders explore polygons. In this math lesson, 5th graders find examples of regular polygons in the classroom and measure the sides of figures to determine if they are regular polygons.

Students create and classify different types of triangles using an online geo-board. They explore the concepts of similar and congruent as they discover how to draw similar and congruent triangles.

Fourth graders explore the definition and properties of parallel lines. This high level lesson has students calculate the slope of the two parallel lines, and draw the lines on a Caretsian coordinate system.

Students create three dimensional shapes using concept maps. In this geometry lesson, students investigate the impact of mental schemas on humans. They collect data on this topic and plot their data on a coordinate plane.

Students explore similar figures. For this surface area and volume lesson, students identify the relationship between the surface area and volume of similar figures.

High schoolers are introduced to the topic of congruence and proportions in Geometry. Using technology, they construct and validate the properties of various geometric figures and identify whether it is congruent or proportion to the...

In this tessellations and transformations worksheet, 10th graders solve 9 different problems that include various types of tessellations. First, they write examples from history of tessellations and name 3 artists. Then, students define...

In this transformations/translation worksheet, students draw transformations based on shapes and vectors of given translations. A reference web site is given for additional activities.

Sixth graders use toothpicks and gumdrops to make prisms and pyramids. This helps them explore the relationship betweeen faces, vertices, and edges.

Students create an artwork that uses organizational principles and functions to solve a visual arts problem. The piece creates the illusion of transparency used to unify a work of art that demonstrates that light advances and darks recede.

Pupils describe the differences between congruence and similarity. After explaining the motions that indicate congruency of two shapes, they complete worksheets to draw lines of symmetry and similar shapes. With straws and twist ties,...

Students create posters about geometric shapes in order to demonstrate their understanding of the different shapes. Students look for pictures in magazines to represent two-dimensional shapes, paste them on a poster, label the shape,...

Students investigate the properties of two and three dimensional objects. In this geometry lesson, students differentiate polygons based on similarity and congruence. They make observation and interpret the data.

Students explore geometry by drawing various shapes in class. In this triangle characteristics instructional activity, students identify the attributes that classify a shape as a triangle and practice using their bodies to create...

Students compare and contrast two dimensional polygons and three dimentional nets by examining the differences in drawings. They create three dimensional shapes and label the faces, edges, and vertices. After creating the shapes, they...

Fifth graders create a net for a given polyhedron. They determine the corresponding polyhedron for a given net. Students investigate several polyhedra (cube, tetrahedron, and one of their choosing) and their corresponding nets. They...

Students investigate the functions of different body systems. They conduct research about the major body systems to attain information. The teacher prepares the room for the lesson. Students walk and talk through each major system as...

Learners identify the parts of three dimensional objects. In this geometry lesson, students find the number of faces, edges and vertices. They differentiate between prisms and polyhedra.

Fourth graders examine faces, edges, and vertices. In this geometry lesson plan, 4th graders participate in classroom activities that require them to compare geometric shapes, figures, and models.
